UPDATE 4.20pm: Bundaberg has received 200mm in six hours and the bulk is yet to come.
A spokeswoman from the Bureau of Meteorology said there is "a fair bit of rain still heading towards Bundaberg".
"Looking at the radar, the bulk of the rain will be this evening," she said.
BoM's latest update has Bundaberg still in the severe weather warning with possible thunderstorms throughout the day.
The region's drenching comes as an upper trough is combines with an inland surface trough producing heaving rain in the Wide Bay and Capricornia.
Cordalba has received 146mm in six hours and Moorland has recorded 141mm.
Tornado-like winds have ripped the roofs off of homes and blown them into power lines, leaving about 4000 Ergon Energy customers on the southside of Bundaberg without power.
Spokesman Rod Rehbein said the freak incident, which reports suggest may have been a waterspout, also propelled trampolines into the power lines, primarily in the area between Walkervale State School and Boreham Park.
Ergon has received more than a dozen reports of fallen power lines in the area.
Crews are responding despite the ongoing downpour, which has caused localised flooding.
Additional crews will depart from the Gladstone area tomorrow at first light to assist local crews in fixing the damage in the Avenell Heights area.
The spokeswoman for BoM said tomorrow there will be more intermittent rain and isolated thunderstorms during the day and clearing in the evening.
UPDATE: Rain is causing havoc throughout the region, with reports of flash flooding in streets and trampolines flying through the air.
In a Facebook post, Bundaberg Police issued a warning to drivers of road closures in the region.
The post said main roads into Agnes Water are currently closed.
Rosedale Rd is also closed due to localised flooding and Fingerboard Rd is closed due to a serious traffic crash.
Booloongie Rd, Gooburrum, is flooded as well as Tantitha St in the CBD, with the bridge underwater.
Targo St has water over the road and Commercial St is also flooded.
Almost 4,000 residents in Bundaberg have lost power due to "damage requiring emergency repairs" to power lines.
It is believed power has gone out in Avenell Heights, Svensson Heights and Walkervale and there are reports a roof has blown off a shed in the Svensson Heights area.
Residents have taken to social media about the unfolding weather events.
It is being reported trampolines are flying through the air and landing in residents' backyards.
The NewsMail has received reports a roof has flown off an Avenell Heights house.
More to come.

EARLIER: THE most significant weather event in six months is developing over Bundaberg, with meteorologists predicting it to intensify tonight.
A developing strong upper trough currently to the north of the region will meet with another trough to dump 30-70mm of rain on the region.
However, if the trough remains north of the region it's possible areas will receive more than double that, between 100-150mm.
A Bureau of Meteorology spokesman said the position of the trough would determine where the forecasted heavy falls will occur, however Bundaberg will see rain.
"Total rainfall is not certain, but tomorrow it's predicted 30-70mm will fall with heavy rain to the south," he said.
The trough is currently developing near the Central Highlands and is predicted to be over Bundaberg about midnight.
The deluge will be welcome news for residents, breaking a 78-day dry spell.
According to records kept by the bureau, it hasn't rained in Bundaberg since July 14, when only 0.4mm fell.
Since the start of what was an unusually dry winter, a mere 16mm has fallen in Bundaberg.
The dry weather had farmers holding their breath and fearing for the next years' crop, while water cartage services reported being run off their feet.
On the 66th day without rain, Bundaberg Canegrowers chairman Allan Dingle said the lack of rain in the past two months was starting to affect crops.
BoM are predicting showers, rain areas and thunderstorms to develop over most of southern inland Queensland, with one or two severe storms with damaging wind gusts and heavy rainfall over the Central Highlands and Coalfields, and eastern parts of the Central West during this afternoon and evening.
Areas from Noosa upwards are expected to receive rain.
